REMINDER-CLOCK.

Specification of Letters Patent.

Patented July 17, 1917.

Application filed June 26, 1916. Serial No. 106,031.

To all whom it may concern Be it known that I, AUGUSTA Y. DAROHE, acitizen of the United States, residing at Chicago, in the county ofCookand State of Illinois, have invented certain new and useful Improvementsin Reminder-Clocks; and

I do hereby declare the following to be a clear, and exact descriptionof the invention, such as will enable others skilled in the art to whichit appertains to make and use the same. i

This invention relates to time controlling especially to annunciatorshaving anadjustable pin; and one object of the same is to produce areminder clocl; whose hour hand arbor carries a contact arm adaptedclose a circuit through an alarm by coming in contact with a pinselectively set by the operator when the alarm is desired.

Another object is ments in the structure of the contact and in ment atquarter-hour intervals.

other object is to produce improvements in means for insulating the dialfrom the remainder of the clock.

With these ob'ects in view the invention consists in the etails'described below and shown in the drawings wherein Figurel is a frontelevation of this clock with most of the dial and its retaining ring andboth'of the hands removed.-

Fig. 2 is a central vertical-section.

Fig. 3 is an enlarged; front elevation of contact arm, and Fig. 4* is aperspective the rear. In the accompanying drawings I have invention asapplied'to a clock which may be of any suitable t adaptedto actuate analarm WhlCh is herewithin the frame of the clock but which may also beof an suitable type and location. 7 A limited in these part'culars, andI have'used reference letters for those elements which 'is to form nopart of the present inventiom That say the frame F carries the clockmechanism C ting access to setting, etc. 1 The frame F also other door Dgivin containing a source 0 has anelectricity E such as a mechanism suchas 'a bell B The frame F ma also'have a seriesof sockets S for pinswhose useis dewithin the upper portion to produce improve-. v

r and of. course also the means for giving it a step by step move- 3 ofthe ype, and is.

.I do not WlSh to be and has a rear door D permit v said mechanism forwinding,"-

access to a chamberwhee 22 h scribed below. This specification is notconcerned with the structure of the clock ex cepting its hour hand H andthe arbor A thereo j 6 The clock C is here shown as attached by screws 1to a plate 2 which is fitted nicely of the frame F, has an annularshoulder3, and a forwardly projecting flange 4 surroundin it. The glass5 5 is carried within a circular i rame 6 which has a rcanwardlyprojecting flange 7 inclosing said flange land removably attachedthereto by suitable means such as screws 8, and this frame has throughit forty-eight holes 9 disposed one opposite each number on the dial oropposite the even hours, and three between each two members so as to beoppositethe quarter hours. One side of the attery E isconnected by awire 10 with the clock G, and therefore it is in electric connectionwith the plate 2 and frame 6, with the arbor A and 'ever, is so aratedfrom the frame 6 by the glass 5.

sheet 14 0f insulation is placed behind the dial so that it cannot comeinto contact with any other mechanism: It is held in place by screws 15as best seen in Fig. l, and these pass through a ring, 18 of insulationbetween the dial and the'shoulder plate 2, and extend into the frame Fwhich will probably be of wood, so that as' a result the dial isentirely insulated. Around its periphery it is provided with holes 19registering with those numbered 9 inthe frame 6, but somewhat smaller.The'pins P have insulated bodiesl6 and bare tips 17,

'the'latter being of a size to pass into the rholes' .19 and throu hthem, whereas the insulated bpdies project" for some distance are 0 asize to rest in the holes 9 but the pins will be out of metalllccontactwith the frame 6 and any portion of the clock mechanism. When the pinsare not being used they are laeedin the sockets S as seen in Fig. 2. 1%wire 20 leads from the battery E to'ther alarm B in the frame F, and isconnected'with the dial 11 whichwith any pinor pins in usthereforebecomes one terminal. Ri 'dly carried by the plate2 is a ratchet avingforty-eight teeth facing in the direction best seen in Fig. 3 which isto V the left or the. reverse of the direction which the hands move. Thearbor A of the hour hand carries the contact hand or arm which, as seenin Fig. 2, stands between the front plate 2 of the clock and the dial11, or

between said plate and the sheetof insula-.

tion 14, and therefore it is not only out of sight but is housed behindthe dial and ina chamber Where it can touch nothing but a the tips, ofsuch pins as are in use. Said contact hand or arm is of metal andcomprises a body 21 enlarged at its inner end into a r ng 23 behlndwhich is a hub 24, and behind the hub in turn is another ring 25carrying a short arm or stub 26 standingabout in alinement with the bodyand on the opposite side of the hub 24 therefrom.

. In the outer end of said stub is formed a notch 27 whose bottom isinclined, or eccenwhich carries a pin 37 projecting to the rear into thenotch 27 A contractile spring 38 connects the finger with the outer endof the body 21 and draws the former normally outward on said body so asto hold the pin in contact with the cam 28; and a pin or stop 39 at theouter end of the finger normally rests against one side of the outer endof the body under the tension of thisspring, so that with the parts atrest they stand as seen in Fig. 3, or in full linesin Fig. 4.

' When this contact arm is applied to the arborA it is preferably set inparallelism with the hour hand H andas the latter makes its rotation t eContact arm turns with it. As the contact arm turns, its body 21 moveswith the arbor whereas the pin 37 engaging a tooth of the ratchet 22prevents the finger 31 from turning with the arbor so long as thisengagement continues. The

' movement of the body, however, moves its stub 26, and asthe cam 28moves under said pin the latter is pressed farther and farther from theaxis of the ratchet wheel until eventually it.disengages the tooththerein the spring 38 meanwhile. being put under slight tension. Theresult is that every fifteen minutes when the finger is released,

it moves forward until its stop 39 contacts with the body 21 In otherwords the construction is such that by the movement of the cam the pin37 is lifted over one tooth of the ratchet 22 and permitted to engagethe next.

When nowit is desired to set the device so as to'use it as. areminderclock (which in the present illustration is carried out by sounding thebell'at B) the operator takes one of the pins P and inserts it oppositethe hour or the quarter hour indicating the-time at which he is tobereminded of something or to be awakened for instance. The tip 17 v-'of the pin fits into and projects through a hole 19 in the dial 11,whereas the insulated body -16 of the pin rests in the-hole 9 in theframe 6 so that the pin stands on a line parallel with the axis of thearbor and is held. at two points while it makes metallic contact onlywith the dial and its tip stands in the chamber between said dial andthe front plate of the clock mechanism. Therevafter as the body memberof the contact hand makes its rotation along with the hour hand,'theouterend of its finger (which is preferably provided with a flexibletongue 40) eventually comes into contact with the tip 17 of the pin.This closes-a circuit from the battery arbor A and the contact arm; tothe "pin P, dial 11, wire 20, bell B, and-back to the battery. The alarmwill therefore be sounded whether it be located within the clock or Ethrough wire 10, clock C,

elsewhere, and it will continue to sound until L the contact arm slipsoff the pin which it must do in fifteen minutes at any rate, or

will do so sooner if the tongue 10 is sulficiently flexible. It is quitepossible that the user may set another pin, say one hole fartherforward, so as to remind him again fifteen minutes later, in case hecannot be aroused easily; and it is obviously possible that the devicehas a wide variety of uses which need not be explained herein. Theinclination of the cam 28 at the bottom of the notch 27 serves twopurposes. F irst it causes the automatic disengagement of the pin- 37from the ratchet 22 at regular intervals whenthe alarm mechanism is notset, 1

and permits the finger 31 to jump with anintermittent movement-forwardas first described above. Second, when the' alarm is set and the tongue40 comes in contact with the pin P, as the finger 31'is swung away.

from the body 21 by such contact the cam 28 retracts or draws saidfinger inward (as the oval hole 34 in its ring 33 permits) and shortensthe period through which the alarm will be sounded at B, rather thansounding the alarm for fully fifteen minutes.
